Hey Rusty, These updated patches in the series return -EFAULT on copy_xx_user errors and also move the copy_from_user into fops_write() instead of it being in send_buf. This enables send_buf to just read from kernel buffers, making it simpler. This also allows write()s to write more to the host in one go, removingthe 4k limitation. I do limit the writes to 32k at once to not put too much

Hi all: This series try to share MSIX irq for each tx/rx queue pair. This is done through: - introducing virtio pci channel which are group of virtqueues that sharing a single MSIX irq (Patch 1) - expose channel setting to virtio core api (Patch 2) - try to use channel setting in virtio-net (Patch 3) For the transport that does not support channel, channel paramters were simply ignored. For

Hi Michael, this series contains a couple cleanups for the virtio_pci interrupt handling code, including a switch to the new pci_irq_alloc_vectors helper, and support for automatic affinity by the PCI layer if the consumers ask for it. It then converts over virtio_blk to use this functionality so that it's blk-mq queues are aligned to the MSI-X vector routing. I have a similar patch in the
